SEVERIN IHALVOIRSENJ or oHIoaGo, ILLINors, AssIeNoR TO THE NEWSPAPER STUFF- WASHINGTON, A CORPORATION or wAsH- ING MACHINE COMPANY, OF SEATTLE, INGTON. I

Application filed July 22, 1925, Serial My invention relates to newspaper stufling machines or the like, and particularly to that part of the machine which operates to open one part or section of the newspaper so as to permit the insertion of other parts or sections.

One of the objects of the invention isto provide a simple, practical; and effective opening head for use in newspaper stufling and like machines.

Another object of theinvention is to avoid interference with the opening of the outside section or article and permit the opening operation to take place independently and effectively without interference with other mechanism.

Other objects of the invention will appear hereinafter.

In the accompanying drawings Fig. 1 is a side elevation of the opening head of the newspaper stufling machine embodying my invention;

Fig. 2 is an end elevation of the same; Fig. 3 is a cross section taken on line 33 in Fig. 1; and

Fig. 4 is aiview similar to Fig. 3, but

with the parts in a different operative position. J

The opening head herein set forth embodies certain general features of construction and operation set forth in the opening head disclosed as part of my pending application for United States Letters Patent Serial No. 562,462, filed May 20, 1922, newspaper stuffing machine, (Case v Referring to the drawings hereinI show part of a newspaper stufiing machine,

chiefly the opening head and related mechanism involving particularly a pairof opening jaws 1 and 2, arranged opposite one another so that the newspaper section or article A to be opened may be interposed between them. A trough?) is also shown,

the trough being more or less below the opening jaws 1 and .2 to receive the lower end of the paper section A as the same is fed down from a holder or stack containing paper sections or articles to be opened, (said holder not being shown herein). I

The head 1 is arranged for reciprocation toward and away from the head 2, as by means of a cam 4: on rotary shaft 5 and connection operated by said cam 4 and conveniently consisting of a rod connected with jaw 1 and link 8 pivotally connected at NEWSPAPEE-STUFFING MACHINE.

9 with rod 7 and also pivotally connected at 10 with sliding member 11 having rollers 12 and 13 arranged to be acted upon'by cam 4, so that saidcam 4 will reciprocate member 11,,link 8 and jaw 1. Link 8 is preferably made in two parts with a springconnection between them, as for example, a coiled spring 14 and threaded screws 15-15 holding the parts of link 8 together and provided ,withadjusting nuts 17 andset nuts 18 and 19 for holding the nuts 17 in place, this spring arrangement being such as to afford a springlike or elastic connection for the jaw 1 to prevent breakage, in case of clogging of the machine or other abnormal operation.

Jaw 2 is arranged for more or less vertical reciprocation crosswise of the path of movementv of jaw 1 and to such end isprovided with an operating lever 20 with a swinging arm 21 and mechanism which need not be described'herein in detail for actuating arm 21- and thereby reciprocating jaw 2. By this arrangement jaw 1 will operate to engage the upper portion of the paper or other article between itself and jaw 2 and then aw 2 will descend so as to push the outer fold, that is the. fold nearest to it,

jaw 2,. downwardly, and therebyseparate said outer fold from the inner one, the one next to jaw 1, and thereby effect the opening of the paper section.

Rollers-.23 and 24; are shown in the lower portion of trough?) adapted to temporarilyengage the lower portion of the paper section. This is for the purpose of holding.

said paper SBC'C1OIll1l'pOSltl0Il in the trough when it is fed down bythe feeding mechanism,that is the paper section is prevented from bouncing up asv it might do if pushed downv rapidly so as to strike the bottom of trough 3. 8

Means are provided by which the engagement of rolls 23 and 24 with the lower portion of the paper section occupies but a short period of time, merely enough to stabilize the paper section in the trough and thereupon the paper section is released, and this engagement and stabilization of the paper section and the release of the same take place before the opening operation is begun by movement of jaws 1 and 2, whereby the desired end of stabilizing the paper section is accomplished but the opening operation is not interfered with, and conseanism conveniently comprising a swinging arm 25 rarried by a rock shaft 26 having an arm 27 pivotally engaged at 28 with a link 29 operated by a cam 30 by means of a roll 31, whereby the operation of cam 30 causes arm 25 to swing sufliciently to cause roller 24 to become engaged with and disengaged from paper section A and to temporarily clamp the latter between said rolls '23 and 24, such engagement being shown in Fig. 3 and such release being shown in Fig. l- The cam 30 and associated mechanism for swinging arm 25 are so connected and related to mechanism for operating jaws 1 and 2 that the. arm 25 is swung to accomplish the result above described, that is to cause the clamping of paper sections bctween rolls 23 and 24: at the exact instant such paper section strikes the bottom of the trough and then to release the paper section immediately before the opening operation is begun by jaws 1 and 2. This result is obtained by properly gear connecting shaft 33 carrying cam 30 with shaft 5 carrying cam 4, shaft 33 operating cam and arm 25, and shaft 5 operating cam 4 and jaw 1, and shaft 36 operating cam 37, and thereby opcrating rock shaft 38 controlling, movement of swinging arm 21, said shaft 36 being gear connected with shaft 33 by means of gears 39, 40, 41 and 42.

From the foregoing it will be seen that the opening head may operate effectively, efficiently and quickly, and without interference of the various mechanisms.

It will be understood that changes and modifications may be made without departing from the spirit of the invention.

'What Iclaim is:

1. In an opening head for stufling machines, the combination with opening means of mechanism for engaging the article to be opened and stabilizing the same and releasing said article before the operation of the opening. means.

2. In an opening head for stutling machines, the combination of opening jaws and means for engaging the article in position to be acted on by the jaws and for stabilizing the article and releasing same before opening operation ofthe jaws begins.

3. The combination with opening jaws of means for actuating the same so as to open the paper section or article and devices for engaging the lower portion of the article to bring the article to a condition of rest prior to the beginning of operation of the opening aws.

4. The combination with the opening jaws and means for actuating the same of rollers to engage the lower portion of the paper article and means for actuating one of said rollers so as to cause the paper article to become clamped between the rollers and tobe released by the same prior to the beginning of operation of the opening jaws.

5. The combination with the opening jaws and means for'actuating the same, of a trough into which the article to be opened may be fed to be held while being opened by the jaws, rollers at the sides of the trough for engaging said article one of said rollers being provided with mounting means by.

which it may be swung toward and away from the other roller so as to clamp the article between the rollers, and means for swinging said mounting means so as to cause the clamping of the article and the release of the same before the opening jaws begin to operate.

6. The combination with a reciprocating head forming'part of the opening device of a stuffing machine, of a spring connection forthe same comprising separate members with a spring interposed between the same, threaded bolts connecting said members milled nuts for adjusting said bolts and set nuts for holding said milled nuts in position.

In witness whereof, Ihereunto subscribe my name this 1st day of July, A. D. 1925.
